Chrysanthemum plant named &#39;Redock Salmon&#39;

ABSTRACT

A Chrysanthemum plant named ‘Redock Salmon’ characterized by its medium sized blooms with salmon ray-florets and yellow-green disc florets.

RELATED CULTIVARS

[0001] ‘Redock Salmon’ is related to ‘Redock Dark (#................)and ‘Redock Orange’ (#.................). These varieties are allmutants of the original ‘Redock’ (unpatented).

BACKGROUND OF THE INVENTION

[0002] ‘Redock Salmon’ is a product of a breeding and selection programwhich had the objective of finding color mutants of ‘Redock’. The newplant of the present invention comprises a new and distinct cultivar ofchrysanthemum plant that is a natural occuring sport of a parentchrysanthemum named ‘Redock’ (unpatented). A comparison with Parentchrysanthemum ‘Redock’ is also made in this application. The newcultivar was discovered as a whole plant mutation in September 1999 byRob Noodelijk in a controlled environment (greenhouse) in RijsenhoutHolland. The first act of asexual reproduction of ‘Redock Salmon’ wasaccomplished when vegetative cuttings were taken from the initialselection in November 1999 in Rijsenhout Holland.

SUMMARY OF THE INVENTION

[0003] The present invention is a new and distinct variety ofchrysanthemum bearing medium sized blooms with salmon ray-florets andyellow-green disc florets.

BRIEF DESCRIPTION OF THE DRAWINGS

[0004] The present invention of a new and distinct variety ofchrysanthemum is shown in the accompanying drawings, the color being asnearly true as possible with color photographs of this type.

[0005]FIG. 1 shows a plant of the cultivar in full bloom.

[0006]FIG. 2 shows the foliage of the cultivar.

DESCRIPTION OF THE INVENTION

[0007] This new variety of chrysanthemum is of the botanicalclassification Dendranthema grandiflora. The observations andmeasurements were gathered from plants grown in April/May in agreenhouse in Rijsenhout Holland in a photo-periodic controlled cropunder conditions generally used in commercial practice. The greenhousetemperatures during this crop were at day-time between 18° C. and 25° C.and at night 20° C. After a long day period of 14 days thephoto-periodic response time in this crop was 47 days. After the longday period to flowering growth retardants were applied 3 times in anaverage dose of 2.5 gram/liter water. No tests were done on disease orinsect resistance or susceptibility. This new variety produces mediumsized blooms with salmon ray-florets and yellow-green disc-floretsblooming on the plant for 4 weeks. This new variety of chrysanthemum hasbeen found to retain its distinctive characteristics throughoutsuccessive propagations however the phenotype may vary significantlywith variations in environment such as light intensity and temperature.To show the phenotype as described ‘Redock Salmon’ can be plantedwithout assimilation lightning (high pressure sodium lamps) between week50 and week 40 of the next year under greenhouse conditions in Holland.With assimilation light (minimum level 2500 lux) it can be planted yearround under greenhouse conditions in Holland.

[0008] From the cultivars known to inventor the most similar existingcultivar in comparison to ‘Redock Salmon’ is ‘Redock Orange’. When‘Redock Salmon’ and ‘Redock Orange’ are being compared the followingdifferences and similarities are noticed: The difference of ‘RedockOrange’ and ‘Redock Salmon’ is the ray-floret color. All othercharacteristics of ‘Redock Orange’ and ‘Redock Salmon’ are similar.

[0009] From other commercial varieties ‘Salmon Reagan’ (USPP 8769) and‘Salmon Elite Reagan’ (not patented yet) are the most similar. Thedifferences between ‘Salmon Reagan’, ‘Salmon Elite Reagan’ and ‘RedockSalmon’ are (1) Flower form and color. The ray-florets of ‘RedockSalmon’ are more upright, less broad, more pointed and more concave. (2)Vigour. Under the same circumstances the plants of ‘Redock Salmon’ are20 cm longer. (3) Response time. The response time of ‘Redock Salmon’ isshorter. (4) The disc-floret size of ‘Redock Salmon’ is smaller. (5)Foliage size and color. The foliage of ‘Redock Salmon’ is bigger andmore yellow-green.

[0010] The following is a description of the plant and characteristicsthat distinguish ‘Redock Salmon’ as a new and distinct variety. Thecolor designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances. The color chart usedin this description is: The Royal Horticultural Society color chart,edition 1995.
